Product Description

Product Description

Company Name: Jinan Deming Power Equipment Co., Ltd

Product Name: Energy Flow Controller

Description:

• Energy flows bi-directionally, allowing for efficient discharge from the battery side to the DC grid or charge from the DC grid side to the battery.


• Fully automatic protection functions ensure safety against overheating, overload, short circuit, and overcurrent.


• Selection of original imported power devices guarantees high-quality performance.


• Fully digital circuit design ensures reliable operation in various environmental conditions, including cold, high temperature, and humid environments.


• All chips used in the energy flow controller are industrial grade, ensuring optimal functionality.


• The main circuit incorporates a DSP chip produced by TI of America, Infineon IGBT module, and Infineon movement for driving and protection, providing a safe and reliable solution.


• The output is automatically synchronized with the grid, resulting in low current harmonic content and no pollution or impact on the grid.


• The grid connected current is controllable and adjustable through closed loop control, allowing for precise power management.


• Wide input voltage range makes the energy flow controller suitable for various applications.


• The system features a comprehensive power protection scheme and perfect self-test and protection function, ensuring reliable operation. In case of system failure, it will stop working to prevent further damage.


• The compact circuit structure ensures space efficiency, while the maximum efficiency of ≥ 96% guarantees optimal energy utilization.


• Protection level can be customized according to the user's needs, providing flexibility and tailored solutions.


• Equipped with an Ethernet interface and standard Modbus TCP communication protocol, allowing for seamless integration into existing systems.
